Step 1: … NettetMathematically the relationship can be represented with the help of following equation −. Y = mX + b. Here, Y is the dependent variable we are trying to predict. X is the dependent variable we are using to make predictions. m is the slop of the regression line which represents the effect X has on Y. b is a constant, known as the Y-intercept.
